Best iPad Apps for 24 Bit Output?

Forgive me if there is already a thread for this, but I'm wondering what apps people are using to play 24 bit music on the iPad through the camera connection kit.

If there is 'specific' thread about this please point me in that direction. I found a number of threads about outputting 24 bit from the iPad, but none that are specifically about the best apps to do this with.
